Six-Degree-of-Freedom Modelling and Simulation for Missile Guidance Systems

The optimal guidance law research of the tactical missile is one of the key technology to improve the missile guidance performance and precision. It is in need of theoretical research and a large amount of simulation computation, so that the optimal guidance law and the parameter of a control system are determined. The space movement of a missile is generally simplified into the plane movement by the scientific researcher so as to do a simulation study, but it is described by the six degree of freedom missile mathematical model in this paper. The movement models of six degree of freedom missile, target and others are derived. There are eleven pieces of models about the missile guidance loop in the simulation software.The paper introduces the design idea and program structure of the software. Using this simulation software, you can do the topic research on the tactical missile guidance problem, trajectory parameter calculation, parameter optimization and guidance performance evaluation. The results of simulation research are given out based on the real parameters of a special ground to air missile.
